<module>CosEventChannelAdmin_ProxyPullConsumer</module>
<modulesummary>This module implements a ProxyPullConsumer interface which acts as a middleman between pull supplier and the event channel.</modulesummary>
<description>
<p>The ProxyPullConsumer interface defines the second step for connecting pull
suppliers to the event channel. A proxy consumer is similar to a normal consumer,
but includes an additional method for connecting a supplier to the proxy
consumer.</p>
<p>To get access to all definitions, e.g., exceptions,
include necessary <c><![CDATA[hrl]]></c> files by using:<br></br><c><![CDATA[-include_lib("cosEvent/include/*.hrl").]]></c></p>
<p>Any object that possesses an object reference that supports the ProxyPullConsumer
interface can perform the following operations:</p>
</description>
<funcs>
<func>
<name>connect_pull_supplier(Object, PullSupplier) -> Return</name>
<fsummary>Connect the pull supplier to the proxy pull consumer</fsummary>
<type>
<v>Object = #objref</v>
<v>PullSupplier = #objref of PullSupplier type</v>
<v>Return = ok | {'EXCEPTION', E}</v>
<v>E = #'CosEventChannelAdmin_AlreadyConnected'{} | #'CosEventChannelAdmin_TypeError'{}</v>
</type>
<desc>
<p>This operation connects PullSupplier object to the ProxyPullConsumer object.
If a nil object reference is passed CORBA standard <c><![CDATA[BAD_PARAM]]></c> exception
is raised. If the ProxyPullConsumer is already connected to a PullSupplier,
then the <c><![CDATA[CosEventChannelAdmin_AlreadyConnected]]></c> exception is raised.
Implementations of ProxyPullConsumers may require additional interface
functionality; if these requirements are not met the
<c><![CDATA[CosEventChannelAdmin_TypeError]]></c> exception will be raised.</p>
</desc>
</func>
<func>
<name>disconnect_pull_consumer(Object) -> Return</name>
<fsummary>Disconnect the ProxyPullConsumer object from the event channel.</fsummary>
<type>
<v>Object = #objref</v>
<v>Return = ok</v>
</type>
<desc>
<p>This operation disconnects proxy pull consumer from the event channel and
sends a notification about the loss of the connection to the pull supplier
attached to it.</p>
</desc>
</func>
</funcs>
